OTPSign is the new USB token realized by applying the innovatory EUTRON-VASCO hybrid technology that combines the advantages of OTP authentication with the potential offered by PKI technology. OTPSign is a device that enables accessing the digital services quickly and safely through the telephone, mobile and Internet channels, besides allowing secure and non-repudiable transactions; it is therefore an extremely flexible, inexpensive and simple solution. This product is ideal for all those entities and organizations that intend to offer their customers secure multichannel accesses to corporate archives, bank data, financial services, health services et cetera).

OTPSign is an M2 secure device: multichannel and multipurpose: Multichannel, thanks to the OTP USB hybrid technology that allows secure access from the fixed and mobile telephone network, from the Internet and via Internet through the USB token Multipurpose, thanks to the EUTRON «all-in-one» technology which combines the OTP component with the smart card cryptography function and the smart card reader, jointly with the USB format flash memory.
